Dunst on red carpet for premiere

Kirsten Dunst and Viggo Mortensen hit the red carpet in London tonight for the premiere of their new thriller, The Two Faces Of January.

The pair star in the film adaptation of the novel of the same name by Patricia Highsmith, author of The Talented Mr Ripley, and led the cast at the Curzon cinema in Mayfair's screening.

It features Mortensen as a con man and Dunst as his wife who try to flee Greece, where they are pretending to be on holiday, after getting caught up in the murder of a police officer.

Oscar Isaac, also at the premiere, plays the young tour guide who gets caught up in the crime when he befriends the couple.

Dunst, 32, said of her co-star: "Viggo is a gorgeous man, so it wasn't that difficult to have chemistry with Viggo. He's really funny, which a lot of people wouldn't expect, and we had a really good time together."

Isaac, 35, agreed: "[Viggo's] such a goofball, that's what I was most excited about, he's very funny and just likes having a good time."

Mortensen, 55, explained why he's often seen in brooding roles despite his jokey reputation: "I don't know, it's just habit, I like these characters to have secrets...

"Also it's what you're offered, no matter how well known you are you can only say yes if someone's invited you. Since I haven't shown that I'm someone who works in comedy, I'm not going to be offered those kinds of roles."

Isaac added he had a great time making the film. "It was the three of us in these incredibly exotic locations having a good time," he said.

"That's why I jumped at the chance because it was really great people in places I'd never been to, so it felt like a paid vacation sometimes."

Dunst said of filming in Greece: "It was great because if we had a day off we'd go swimming in the sea and the weather was perfect."

Director Hossein Amini was on the red carpet too, along with another of the film's stars, Daisy Bevan.
